Israeli aircraft struck in Gaza and Palestinians fired rockets at Israel on Saturday after an Israeli operation against the Islamic Jihad militant group ended more than a year of relative calm along the border. 

Israel on Friday killed one of the group’s senior commanders in a surprise daytime air strike on a high-rise building in Gaza city which drew rocket salvoes in response. On Saturday, Israel said it struck Islamic Jihad militants preparing to launch rockets. Additional bombings targeted three houses, witnesses said, flattening at least one as the sounds of more explosions rocked Gaza city.
